I've noticed many others have had the same problems... I'm one of those guys that has to take things apart to see what makes them work, knowing only a little and always getting myself in over my head. Yesterday the computer decided to quit while sitting there quietly running. It does not power up. The little green light on the board is on. I swapped out power supplies, same thing, no response. I jumped the green power feed on the harness to the board with a ground and the fan on the power supply comes on. I disconnected the power switch to the MB and jumped the terminals on the board, nothing. I disconnected all the flotsam and jetsam from the MB and then tried to power up, no beeps, no fan on the cpu, nothing except that evil green light. I disconnected the power cord, pulled the bios battery out, jumped the bios terminals to clear it, then put everything back, no difference. This is an intel d865gvhz MB which I replaced just a year ago, to fix a seabreeze MB that did the same thing! Any thoughts for a backyard wanabe?
